| Research Abstract |
First, the control method of membrane thickness and diameter of microcapsules was roughly developed. Secondary, the in-situ observation method of tensile fracture behavior of microcapsules was constructed, and tensile strength of prepared microcapsules was evaluated as 77 to 220 [MPa]. Finally, small holes were formed on the surface of microcapsules using the "removing-after-mixing" method of third phase magnetic materials or the direct piercing method of small needle. The flowing behavior of core materials from holes by static and cyclic loading was observed in-situ.
